I've had a few instances over the last few years where I've had to go to a funeral/wakes but due to family dynamics I've been friendly with some and not others within that family.
Eg i was very friendly with 2 sisters, lets call them Mary and Mungo. There was also an older sister who I never liked but was polite to, out of necessity, she is Midge. The 2 younger sisters Mary and Mungo fell out years ago and I became a casualty of this with Mungo for no real discernible reason but i remained very good friends with Mary. I did try to ring Mungo for a significant birthday after this, but never got a reply.
So when their father passed away a few years ago, at his funeral/wake, rightly or wrongly, I avoided Mungo as she had blown me out years before, and i thought , well if i meant so little then it wont matter if i dont greet her now. There also had been alot of bad blood since between her and Mary and I was disgusted at some of Mungos actions.
More recently Mary had also fallen out with her older sister Midge. So at the wake when i approached Midge to offer my condolences, she flinched and withdrew when i went to give her a hug. In the ensuing days Midge totally stopped speaking to me. Honestly I didnt care about that because I had never liked her, she was/is a nasty nasty person, very self absorbed and she had always treated my friend very badly.
But, in all honesty, despite how Mungo had treated me I always have thought I should have just politely shook her hand and moved on, but i didnt want to give her another opportunity to ignore or be rude to me again, possibly similarly to how her older sister treated me. At the same event another friend of Mary's and I approached Mungo and she was VERY STANDOFFISH with her.
Because it may seem that Mary was the one to fall out with everyone, this was very much not the case, it was only when she started standing up for herself she fell out with her older sister. Midge and Mungo NEVER got on and were always fighting. The family dynamic was always very strained between them all.
So that l'm not drip feeding there is a muckier side to this whole story and it would be outing to explain the dynamics within the family and relationships so ive kept it as superficial as i can.
What is the proper etiquette here, was I completely unreasonable or not ? How to others handle this ?
